T0 all whom it may concern: are not important. On this understanding Be it known that I, FRANK II. VW'HIrPLn, the gist of the invention is as follows: a citizen of the United States, residing at The pump runner by preference has a Visalia, in the county of Tulare and State hub 1 adapted to be removably engaged with 604 of California, have inventedcertain new the shaft S of the motor in any suitable way and useful Improvements in Pumps; an I as by tapering the latter atthe point 2 and do declare the following to be a full, clear, forcing the hub thereon by a nut 3 as shown. and exact description of the invention, such The shaft may be reduced and extended as as will enable others skilled in the art lto ata; through this nut and across the inlet el- 65 which it apperta'ins to make and use the bow or nozzle I, and its remote end I prefer Same, to mount in a thrust bearing T.

These variousobjectsare carried out by avoids the necessity that the pump shall 'constructing the device in the manner herehave a 'shaft of its own, and therefore the inafter more fully described and claimed, use of a coupling betweenv the motor shaft and as shown in the drawing hereto attached and the pump shaft is also avoided. This whereon the motor casing is illustrated in not only simplifies 'matters andreduces .cX- so,

The letter T designates broadly a sage 10, lunder the valve 11and through the thrust bearing whosedetails'of construction passage 12 to the channell, in which lat-x ter it forms a water seal and prevents air from being sucked in through the bearing 14 and driven through said bearing 15 tovv'ard the motor. For carrying the Water Within the channel 13 back to the center of the runnerR, the vided with a spiral groove 16, andthe inner end of this groove communicates With an annular space 17 around the hub as shown in the drawings. Therefore there is a constant circulation of water from, the channel Within the rim through the passage to the channel 13 around the bearing, and from the latter back to the center of the runner, and while the water is passing through this course it cools the bearings and keeps them clean. lf the pump should be throwing too much sand I would prefer to close the valve y1l, at least temporarily.

For lubricating purposes oil may be admitted through a pipe 20 to one portion of the bearing or its babbitt at 15. At the inner end of this portion 1 also preferably form an annular channel 21 which communicates through a passage 22 with an exhaust pipe 23, and this channel catches any oil or water which may pass through the inner section of the bearing, and therefore prevents it from being driven or drawn into the motor. This detail protects the ceils of the latter, and l find it of advantage. Around the shaft S and at a 'point to be projected into the channel 21 when the front casing is applied to the motor casing., l preferably secure a collar 25 as shown; these parts are assembledv this collar will stand Well within the casing of the motor. The parts are otherwise of any preferred construction. and the materials and proportions are obviously7 not important.

What is claimed as new is:

1. The combination with a rotary motor having an extended shaft; of a centrifugal pump whose runner is mounted on said shaft and whose casing has a two-part bearing for y the shaft, an annular channel formed around the latter intermediate the parts of the bearing, and a passage-Way leading from its rim to said channel, the Walls of said passageyvay beingformed integrally with said caslng having an extended shaft; of a centrifugal pump whose runner is mounted on said shaft bearing 14 may be proj passa ring; of a centrifugal and when.-
